Conversion formula

The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:

1 kt = 1.6878098570997 ft/s

To convert 343.4 knots into feet per second we have to multiply 343.4 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:

1 kt → 1.6878098570997 ft/s

343.4 kt → V_(ft/s)

Solve the above proportion to obtain the velocity V in feet per second:

V_(ft/s) = 343.4 kt × 1.6878098570997 ft/s

V_(ft/s) = 579.59390492805 ft/s

The final result is:

343.4 kt → 579.59390492805 ft/s

We conclude that 343.4 knots is equivalent to 579.59390492805 feet per second:

343.4 knots = 579.59390492805 feet per second

Alternative conversion
